Chemical Structure

<SC>L</SC>-异亮氨酸-1-<SUP>13</SUP>C CAS 81202-01-9 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 <SC>L</SC>-异亮氨酸-1-<SUP>13</SUP>C.

CATO supplies <SC>L</SC>-异亮氨酸-1-<SUP>13</SUP>C (CAS 81202-01-9), a certified reference material (molecular formula C5[13C]H13NO2, MW 132.17 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, <SC>L</SC>-异亮氨酸-1-<SUP>13</SUP>C is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.17 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 <SC>L</SC>-异亮氨酸-1-<SUP>13</SUP>C 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.
