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 (2S)-2-Amino-3-{[(tert-butoxy)carbonyl]amino}propanoic acid hydrochloride.
(2S)-2-Amino-3-{[(tert-butoxy)carbonyl]amino}propanoic acid hydrochloride (CAS 1820572-31-3), molecular formula C8H16N2O4HCl and molecular weight 240.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (2S)-2-Amino-3-{[(tert-butoxy)carbonyl]amino}propanoic acid hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (2S)-2-Amino-3-{[(tert-butoxy)carbonyl]amino}propanoic acid 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.
