Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5459-58-5 F9H6L20VOH Butyl cyanoacetate Acetic acid, cyano-, butyl ester Acetic acid, 2-cyano-, butyl ester 4-02-00-01891 (Beilstein Handbook Reference) BRN 1761735 n-Butyl cyanoacetate EINECS 226-730-1 UNII-F9H6L20VOH EC 226-730-1.

5459-58-5 F9H6L20VOH Butyl cyanoacetate Acetic acid, cyano-, butyl ester Acetic acid, 2-cyano-, butyl ester 4-02-00-01891 (Beilstein Handbook Reference) BRN 1761735 n-Butyl cyanoacetate EINECS 226-730-1 UNII-F9H6L20VOH EC 226-730-1 (CAS 5459-58-5) is a high-purity analytical reference standard with the molecular formula C7H11NO2 and a molecular weight of 141.17 g/mol.

The molecular framework of 5459-58-5 F9H6L20VOH Butyl cyanoacetate Acetic acid, cyano-, butyl ester Acetic acid, 2-cyano-, butyl ester 4-02-00-01891 (Beilstein Handbook Reference) BRN 1761735 n-Butyl cyanoacetate EINECS 226-730-1 UNII-F9H6L20VOH EC 226-730-1 (C7H11NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 5459-58-5 F9H6L20VOH Butyl cyanoacetate Acetic acid, cyano-, butyl ester Acetic acid, 2-cyano-, butyl ester 4-02-00-01891 (Beilstein Handbook Reference) BRN 1761735 n-Butyl cyanoacetate EINECS 226-730-1 UNII-F9H6L20VOH EC 226-730-1 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.
