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 Ac-Orn-OH.
CATO supplies Ac-Orn-OH (CAS 6205-08-9), a certified reference material (molecular formula C7H14N2O3, MW 174.20 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ac-Orn-OH is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.20 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.
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.
CATO manufactures Ac-Orn-OH under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
