Calcium Acetate CAS 62-54-4

Longchang sourcing page for Calcium Acetate / calcium diacetate, CAS 62-54-4. Send the required material form, 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

Material form and assay basis

Calcium Acetate may be specified as anhydrous material or a hydrate. The form affects molecular weight, water context and assay calculations. Every request should state the required form and whether assay is calculated as supplied, after drying or on an anhydrous basis.

Do not compare two offers from a product name and percentage alone. Compare the controlled specification, methods, material form, basis, units, impurity profile and applicable lot COA.

Information to request for qualification

Food, E263 and pharmaceutical boundaries

CAS 62-54-4 establishes substance identity; it does not establish food, pharmaceutical, feed or another regulated grade. E263 is the EU food-additive number for Calcium Acetate, but compliance depends on the exact material, regulatory specification, food category, use condition, destination market and current evidence.

U.S. 21 CFR 184.1185 and EU Regulations 1333/2008 and 231/2012 contain jurisdiction-specific records. They do not prove that the current Longchang material complies. State the intended use so the required specification, methods, declarations and buyer qualification can be assessed.

Named Calcium Acetate capsules on DailyMed are finished prescription products. Their dosage form, label and approval do not convert an unspecified raw material into an approved medicine or justify patient-use instructions on this page.

Read the Calcium Acetate E263 food-use and regulatory guide before defining a regulated-food request.

Historical source-record fields

The previous product page displayed the following fields 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 legacy infant-food dosage and broken structure image are not valid qualification evidence. Use current regulations, controlled specifications and buyer approval instead.

Application and supplier qualification

Evaluate Calcium Acetate only against a defined technical function and use context. Confirm material form, assay basis, impurity profile, process performance, regulatory scope, safety controls and finished-product requirements. General lists such as food processing, formulation or industrial synthesis do not prove that a particular lot is suitable.

For identity, formula, hydrate and specification questions, read the Calcium Acetate formula, properties and sourcing guide.

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.
