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 DL-Alanine Methyl Ester Hydrochloride.
CATO supplies DL-Alanine Methyl Ester Hydrochloride (CAS 13515-97-4), a certified reference material (molecular formula C4H9NO2HCl, MW 139.58 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, DL-Alanine Methyl Ester Hydrochloride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), DL-Alanine Methyl Ester Hydrochloride 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.
