Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3 inverted exclamation mark ,6 inverted exclamation marka-Diacryloxyspirobenzo[c]-furan[1,9 inverted exclamation mark ]xanthen-3-one 7262-39-7 Diacryloyloxyfluorescein Fluorescein O,O inverted exclamation marka-diacrylate.

3 inverted exclamation mark ,6 inverted exclamation marka-Diacryloxyspirobenzo[c]-furan[1,9 inverted exclamation mark ]xanthen-3-one 7262-39-7 Diacryloyloxyfluorescein Fluorescein O,O inverted exclamation marka-diacrylate (CAS 7262-39-7), molecular formula C26H34O7 and molecular weight 458.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3 inverted exclamation mark ,6 inverted exclamation marka-Diacryloxyspirobenzo[c]-furan[1,9 inverted exclamation mark ]xanthen-3-one 7262-39-7 Diacryloyloxyfluorescein Fluorescein O,O inverted exclamation marka-diacrylate (C26H34O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 3 inverted exclamation mark ,6 inverted exclamation marka-Diacryloxyspirobenzo[c]-furan[1,9 inverted exclamation mark ]xanthen-3-one 7262-39-7 Diacryloyloxyfluorescein Fluorescein O,O inverted exclamation marka-diacrylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
