Isobutyl formate (2-methylpropyl methanoate) is an organic ester with the chemical formula C 5 H 10 O 2. It is formed by the Fischer esterification of isobutanol with formic acid, with the aid of an acid catalyst. It is used as a flavor and fragrance ingredient because of its odor which is sweet, ethereal, and slightly fruity. [2] [3]

Using cordless phones that do not use the 2.4 GHz band. Using the 5 GHz band. DECT 6.0 (1.9 GHz), 5.8 GHz or 900 MHz phones, commonly available today, do not use the 2.4 GHz band and thus do not interfere. VoIP/Wi-Fi phones share the Wi-Fi base stations and participate in the Wi-Fi contention protocols.
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Bis[2,4,5-trichloro-6-(pentyloxycarbonyl)phenyl]oxalate (also known as bis(2,4,5-trichloro-6-carbopentoxyphenyl) oxalate or CPPO) is an organic compound with the formula (C 5 H 11 O 2 CC 6 HCl 3 O) 2 C 2 O 2. A white solid, it is classified as a diester of oxalic acid. It is an active ingredient for the chemiluminescence in glowsticks. [1]
Valeric acid or pentanoic acid is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 (CH 2) 3 COOH. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. It is found in the perennial flowering plant Valeriana officinalis, from which it gets its name. Its primary use is in the synthesis of its esters.
The IUPAC name of 2,2',3,3',4,4'-hexachlorobiphenyl is 1,2,3-trichloro-4-(2,3,4-trichlorophenyl) benzene and its molecular formula is C 12 H 4 Cl 6. It is a light yellow, soft, sticky resin and has a boiling point of 385-420 °C. Its flash point lies around 141 °C and its melting point around 150 °C. [1]
