Chemical Structure

Calcium Stearate CAS 1592-23-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Calcium Stearate.

CATO supplies Calcium Stearate (CAS 1592-23-0), a certified reference material (molecular formula C18H35O2Ca, MW 323.55 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Calcium Stearate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Calcium Stearate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
