Verified chemical identity
| Nombre del producto | Calcium Citrate Tetrahydrate |
|---|---|
| Sinónimos | Tricalcium dicitrate tetrahydrate; calcium citrate tribasic tetrahydrate |
| CAS Registry Number | 5785-44-4 |
| EC number | 629-915-9 |
| Formula | C12H18Ca3O18 or Ca3(C6H5O7)2·4H2O |
| Peso molecular | 570.5 g/mol (PubChem; commonly 570.51 in regulatory specifications) |
| Formula-derived calcium fraction | Approximately 21.1%; calculation only, not a current specification or lot result |
| InChIKey | LNIZKKFWMDARJV-UHFFFAOYSA-H |
| Identity sources | PubChem CID 5282392; ECHA |
CAS and hydrate must match the purchase specification
CAS 5785-44-4 explicitly identifies the tetrahydrate record in PubChem. CAS 813-94-5 is a separate tricalcium dicitrate record with formula C12H10Ca3O14 and molecular weight 498.4 g/mol. Food-regulatory specifications may cite CAS 813-94-5 while describing the tetrahydrate, so a buyer should never rely on the generic name “calcium citrate” or a CAS field alone.
State the requested name, CAS record, hydrate/form, formula or assay basis and applicable regulatory or customer standard. If the requirement is specifically CAS 813-94-5, review the separate Calcium Citrate CAS 813-94-5 product record and request form-matched documents rather than assuming interchangeability.
Information to request for qualification
| Qualification item | What to request or define |
|---|---|
| Identity and hydration state | Controlled product name, CAS, identity methods, tetrahydrate designation and acceptance criteria |
| Ensayo | Required range, analytical method, dried/anhydrous/as-supplied basis and applicable lot result |
| Water / loss on drying | Named method, temperature/time, calculation basis, limit and applicable lot result |
| Elemental calcium | Required reporting basis, method, units and acceptance range; do not substitute the 21.1% theoretical calculation for a test result |
| Impurity profile | Applicable oxalate, fluoride, arsenic, lead, mercury, insoluble matter, metals or buyer-specific fields |
| Microbiología | Applicability, methods, sampling plan, limits and applicable lot results |
| Regulatory evidence | Exact jurisdiction, additive/technical function, monograph, food category or customer standard and required declarations |
| Documents | Current specification, applicable lot COA, current SDS and requested questionnaires/statements |
| Commercial details | Sample, MOQ, current availability, quotation validity, packaging and destination-specific lead time |
E333, JECFA and U.S. food boundary
The EU E333 family includes mono-, di- and tricalcium citrate. E333(iii) describes tetrahydrated tricalcium citrate. JECFA’s INS 333 record and U.S. 21 CFR 184.1195 also provide food-use identity and specification context.
These records do not establish that the current Longchang material complies with E333, JECFA, Food Chemicals Codex or a buyer’s destination-market requirements. The cited food records commonly use CAS 813-94-5 while describing tetrahydrate, which makes exact document matching essential. State the intended technical function, food category, market and required standard so suitability can be reviewed.
Read the Calcium Citrate Tetrahydrate identity and sourcing guide for the formula, molecular-weight and CAS/hydrate boundary.
Historical source-record fields
The previous product page displayed the fields below without a visible current controlled specification number, complete method set, lot identity, effective date or approval status. These values are historical sourcing context only. They are not a current Longchang specification, lot result, grade statement, packaging commitment or regulatory declaration.
| Historical field | Old page value | Current evidence required |
|---|---|---|
| Apariencia | Polvo blanco | Controlled wording, identity tests and acceptance criteria |
| Ensayo | 97.5–100.5% | Current method, hydration/drying basis, range and applicable lot result |
| Pérdida por secado | 10.0–13.3% | Current method, conditions, basis, limit and applicable lot result |
| Inorganic / impurity fields | Old arsenic, lead, fluoride, heavy-metal and acid-insoluble-matter limits | Current applicability, methods, units, limits and lot results |
| Microbiología | Old TPC, yeast/mold, Salmonella, E. coli and S. aureus fields | Current applicability, methods, sampling plan, limits and lot results |
| Embalaje | 25 kg/bidón | Current package size, construction, lining, closure, pallet and destination |
The removed 404 structure image and unsupported legacy-use wording are not qualification evidence.
Application and supplier qualification
Evaluate the material only against a defined technical function and use context. Confirm identity, hydration state, assay basis, impurity profile, process performance, regulatory scope, safety controls and finished-product requirements. A generic application list does not prove that a current lot is suitable.
Safety and handling boundary
This page is not a substitute for an SDS or site-specific risk assessment. Request the current supplier SDS and use it with local regulations and the buyer’s procedures to define classification, receipt, storage, transfer, processing, transport and disposal controls for the material supplied.
