771-97-1 Usage
Uses
Used in Analytical Chemistry:
2,3-Diaminonaphthalene is used as a derivatization reagent for the determination of selenium at low detection limits, making it a valuable tool in the field of analytical chemistry.
Used in Fluorometric Assays:
2,3-Diaminonaphthalene is used in a reaction similar to that of DAF-FM, reacting with the nitrosonium cation that forms spontaneously from NO to form the fluorescent product 1H-naphthotriazole. This has led to the development of a rapid, quantitative fluorometric assay that can detect nitrite levels from 10 nM to 10 μM and is compatible with a 96-well microplate format.
Used in Material Science:
2,3-Diaminonaphthalene is used in the preparation of precursors for multi-layer 3D materials comprising chiral organic sandwich compounds, contributing to the advancement of material science and the development of novel materials with potential applications in various industries.
Reactions
2,3-diaminonaphthalene (DAN) is a fluorometric probe for nitrite. It reacts with nitrosonium, which is formed from nitrite at low pH, to form the fluorescent dye 1 H-naphthotriazole. This method can be used to detect 10 nM to 10 uM of nitrite (NO2-) and is compatible with 96-well format.Reaction of 2,3-Diaminonaphthalene with NO2.
Purification Methods
Crystallise the diamine from water, or dissolve it in 0.1M HCl, by heating to 50o. After cooling, the solution is extracted with decalin to remove fluorescent impurities and centrifuged. [Beilstein 13 IV 346.]
Check Digit Verification of cas no
The CAS Registry Mumber 771-97-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 771-97:
(5*7)+(4*7)+(3*1)+(2*9)+(1*7)=91
91 % 10 = 1
So 771-97-1 is a valid CAS Registry Number.

, p. 821 - 828 (2017/05/26)
Thirteen new compounds belonging to series 2-amino-6-(5,10-dioxo-2,3-diphenyl-5,10-dihydrobenzo[g]quinoxalin-7-yl)-4-(substituted)phenylpyridine-3-carbonitrile (6a-m) were synthesized by multistep synthetic scheme. The newly synthesized compounds were screened for their antimycobacterial activity by L.J. Slope (Conventional) Method. Compound 6h with 4-N(CH3)2 group at phenyl ring of above mentioned position has been reported as most active antimycobacterial compound and compound 6k with 4-CH3 substitution at phenyl above mentioned position has been reported as the least active antimycobacterial compound.

, p. 25 - 31 (2019/01/16)
Eleven new compounds diones namely, 7-[3-(substituted) phenylprop-2-enoyl]-2,3-diphenyl- 5H,10H-benzo[g]quinoxaline-5,10-dione (6a-k) were synthesized by multistep synthetic scheme. The newly synthesized compounds were submitted for their in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv by L.J. Slope (Conventional) Method. Compound 6e having 4-OCH3 at phenyl ring attached to 3-position of prop-2-enoyl group has been observed as the most active antimycobacterial compound, while compound 6h having 4-CF3 group on the above-mentioned position has been observed as the least active antimycobacterial compound of the newly synthesized series.
