1. A method of sequencing a nucleic acid molecule comprising:
(a) incorporating in series a plurality of nucleotides into a primer hybridized to the nucleic acid molecule to create an extension strand, wherein each nucleotide comprises:
(i) a cleavable moiety covalently bound to the 3′ oxygen of the nucleotide, said cleavable moiety having the formula -L1P-S—S—R6P (I); wherein, L1P is a substituted methylene, wherein L1P is substituted with a substituted or unsubstituted alkyl, or a substituted or unsubstituted heteroalkyl; R6P is unsubstituted C1-C4 alkyl; and
(ii) a detectable moiety attached to said nucleotide via a covalent linker, wherein said covalent linker comprises
![]() wherein, R102 is unsubstituted C1-C4 alkyl; and
(b) detecting the detectable label of the incorporated nucleotide to identify the incorporated nucleotide in the extension strand, thereby sequencing the nucleic acid molecule.
