Calcium Citrate Tetrahydrate CAS 5785-44-4

Longchang sourcing page for Calcium Citrate Tetrahydrate / tricalcium dicitrate tetrahydrate, CAS 5785-44-4. Send the intended application, destination market, target specification and quantity to request the current specification, analytical methods, applicable lot COA, SDS status, sample availability, packaging, MOQ, availability and confirmed lead time.

Verified chemical identity

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

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.

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.
