309752-65-6 Usage
General Description
6-(Hydroxymethyl)-2-naphthol, also known as flavonol yellow or C.I. 26410, is a fluorescent yellow dye commonly used in histology and cytology staining techniques. It is an aromatic compound with a naphthol and hydroxymethyl group. This chemical is insoluble in water but soluble in alcohol and acetone. 6-(Hydroxymethyl)-2-naphthol is a useful reagent for the detection of aldehydes and ketones and is often used as a staining agent in biological research and diagnosis. It has a strong absorption in the ultraviolet region, making it suitable for fluorescence microscopy and imaging applications.
Check Digit Verification of cas no
The CAS Registry Mumber 309752-65-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,7,5 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 309752-65:
(8*3)+(7*0)+(6*9)+(5*7)+(4*5)+(3*2)+(2*6)+(1*5)=156
156 % 10 = 6
So 309752-65-6 is a valid CAS Registry Number.

The design and synthesis of a photoactivatable HNO donor incorporating the (6-hydroxynaphthalen-2-yl)methyl (6,2-HNM) photocage coupled to the trifluoromethanesulfonamidoxy analogue of the well-established HNO generator Piloty's acid is described. The photoactive HNO donor stoichiometrically generates HNO (～98%) at neutral pH conditions, and evidence for concerted C-O and N-S bond cleavage was obtained. The methanesulfonamidoxy analogue primarily undergoes undesired N-O bond cleavage.
