FAQ - Technical & Supply Chain
-
Q:
What substance does Inositol Niacinate, CAS 6556-11-2, identify?
A: Inositol Niacinate, CAS 6556-11-2, is an inositol ester of nicotinic acid, also called inositol hexanicotinate. The two names identify the same substance; do not infer a BP standard, assay, health effect or dosage form from the chemical identity alone. -
Q:
What intended applications should be confirmed before procurement?
A: Confirm the intended application and local regulatory suitability before procurement. The page does not establish a therapeutic, dietary-supplement or compendial claim, so the buyer must assess whether the offered grade and documents support the specific use. -
Q:
Which specifications should be agreed for Inositol Niacinate?
A: Confirm offered physical form, assay and impurity requirements, packaging, intended application and document needs. Ask for the assay basis and relevant impurity limits on the batch specification, and do not compare quotations without aligning the specification. -
Q:
What packaging and physical form should be specified?
A: Confirm the offered physical form in the current product-specific specification and select packaging compatible with the offered form and destination requirements. Request the current product specification for the exact material being quoted. -
Q:
What are the typical appearance, melting range and solubility of Inositol Niacinate?
A: Inositol niacinate CAS 6556-11-2, formula C42H30N6O12 and molecular weight 810.72, is normally a white or off-white crystalline powder with a melting range commonly near 254-262 C. It is essentially insoluble in water, so confirm the offered form, melting range and assay basis rather than assuming compendial or supplement status.
